Boneham SP00008879 Press Fit Headless Drill Bushing

Product Description

The BONEHAM SP00008879 is a press fit headless drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Manufactured from steel with a hardness of 60 to 65 HRC, this bushing provides long service life under repeated tooling contact. It features a 27/32-inch inside diameter and a 1-3/8-inch body outside diameter, with an inside diameter tolerance of +0.0002 to +0.0006 inches for accurate tool guidance. The headless press fit design seats flush in the jig plate and requires no separate liner bushing. It is installed and serviced by machinists and tooling specialists in production and fabrication environments.

This bushing is suited for fixed jig applications where the drill bushing will not need routine replacement during a production run. The press fit retention method locks the bushing directly into the jig plate, making it appropriate for single-operation or dedicated fixture setups in metalworking shops, manufacturing facilities, and job shops. With a 5/8-inch overall length, the part fits standard jig plate thicknesses common in light-to-medium duty tooling fixtures. It conforms to ANSI standards for drill bushing dimensions and tolerances.

Key Features

• Press fit headless design seats flush with the jig plate surface for unobstructed tool entry
• Steel construction with 60 to 65 HRC hardness resists wear from repeated drill and reamer passes
• 27/32-inch inside diameter with tight tolerance of +0.0002 to +0.0006 inches for accurate tool guidance
• 5/8-inch overall length suits standard jig plate thicknesses
• ANSI-compliant dimensions for interchangeability with standard drill jig hardware
• Non-renewable design provides a permanent, stable fit in fixed tooling fixtures

Compatibility

Designed as an OEM-style replacement or original fit for press fit headless drill bushing applications conforming to ANSI drill bushing standards with a 27/32-inch inside diameter and 1-3/8-inch outside diameter.

Installation Notes

Press fit drill bushings are installed by machinists using an arbor press or hydraulic press to seat the bushing flush and square in the jig plate bore. Power to any associated machinery must be off and the workpiece must be secured before pressing the bushing into place. Do not hammer the bushing directly, as uneven force can distort the bore or damage the seating surface. Once pressed in, this bushing is not intended for removal and reuse.
